Title: Improvements in the process of producing photographic material for multi-colour screen pictures
IPC: G03C7/04
Filed: 1934-04-12
Abstract: 436,723. Colour photography. WILMS, H., 8, Bovermannstrasse, Dortmund, Germany. April 12, 1934, Nos. 11077, 11078, and 11079. Convention dates, April 21, 1933, Dec. 19, 1933, and March 3, 1934. [Class 98 (ii)] Relates to the production of photographic material for multicolour screen pictures wherein the light-sensitive coating is selectively sensitized under the respective screen elements by successive application of the elements of different colour, as described in Specifications 393,797 and 402,231, and consists in protecting the applied elements against the action of selective sensitizers and colouring matters subsequently used, either by a hardening, tanning or mordanting treatment, or by covering with a protective coating. Thus, as shown in Fig. 2, a support carrying a blue-sensitive coating b is first printed with blue elements c, in fatty ink admixed with a drier, and, after drying, a temporary, fatty ink resist is applied leaving gaps e which are sensitized for and coloured red and hardened with formalin; the temporary resist is then removed by a solvent and the remaining gaps f are sensitized and coloured green. The green elements need not be hardened. To counteract the increased sensitiveness to blue by the colour sensitizations, a yellow colour is applied between the elements b ; this colour may be subsequently removed. Fig. 5 shows a modification in which a temporary screen p of fatty elements is applied to the coating, leaving gaps q which are sensitized and coloured red and hardened by formalin; the screen p is then removed and the other elements are produced in a similar manner. Fig. 8 shows a further modification in which the screen elements are incorporated in a top coating u. Colouring may be effcted by suitable dyes which may be mordanted, e.g. by treatment with stannous chloride or aluminium sulphate. Instead of a hardening or tanning treatment, the elements may be protected by a coating of shellac, casein, para-rubber &c. which coating is removed by a suitable solvent after completion of the colour screen. Yellow elements may be employed in place of green, and may be subsequently converted to green, e.g. by including a component of a blue or green dye. Fig. 9 shows an apparatus for continuous production of the material shown in Fig. 8. The sensitized material 2 passes from a spool 1, under a printing roll 3 which applies the fatty resist, then through sensitizing, colouring, hardening and resist-solvent baths 6, 7, 8, 9 to a second printing-roll 3<1> &c. A drying-device 10 is provided after each bath.

Abstract: 1490122 Preparing tertiary alkyl phosphine oxides HOECHST AG 18 March 1975 [22 March 1974] 11178/75 Heading C2P Tertiary phosphine oxides of the formula in which R and R<SP>1</SP> are the same or different alkyl groups having 1 to 6 carbon atoms are obtained by rearranging tertiary mono-(hydroxymethyl)phosphines of the formula in the presence of BF 3 .etherate as catalyst at a temperature within the range - 10‹ to + 250‹ C. and in the absence of oxygen, water and monohydric alcohols. The process is preferably effected at 90-180‹ C. and may be carried out in an inert, polar or non-polar organic solvent or diluent which may be a previously prepared phosphine oxide of the above formula. The reaction is also advantageously carried out under an inert gas, e.g. N 2 , CO 2  or argon. In an embodiment the process is carried out by starting with a secondary phosphine RR<SP>1</SP>PH reacting the latter at atmospheric pressure and at a temperature not exceeding 40‹ C. with formaldehyde, paraformaldehyde or trioxane in the presence of an inert polar organic solvent and then subjecting the resulting tertiary monohydroxymethyl phosphine, without separation thereof, to the rearrangement process in the presence of the catalyst in the defined manner. Examples are given for the production of trimethylphosphine oxide.

Title: Improvements in and relating to a method and system for measuring the property of a dielectric material
IPC: G01R17/16
Filed: 1965-03-17
Abstract: 1,103,231. Measuring moisture content electrically; measuring dielectric constant. INDUSTRIAL NUCLEONICS CORPORATION. March 17, 1965 [March 17, 1964], No. 11331/65. Headings G1N and G1U. A property, such as moisture content, of a dielectric 20, Fig. 1 is measured by applying an A. C. signal from an oscillator 10 to a pair of capacitor plates 14, 16 associated with the dielectric, backing of the voltage across the capacitor with a phase inverted voltage derived from the oscillator by means of a phase inverter 24 and a variable capacitor 26, so that the net signal at 22 is zero in the absence of any dielectric material, and comparing at 30 the phase of this net signal when a dielectric is present with the phase of the oscillator, to indicate the property of the dielectric independently of the effect of its mass. The phase inverter comprises an amplifier (34 Fig. 2 not shown) having equal input and feedback capacitors 36, 38. The signal at 22 is supplied to a detector amplifier 28, and thence to a series of gain-controlled amplifiers (44, 46, 48 Fig. 2 not shown), or to a clipper (101, Fig. 4 not shown), to give a constant amplitude signal the phase of which varies with the dielectric property being measured. In the gain-controlled amplifier embodiment, the constant amplitude signal (81, Fig. 2 not shown) is compared in magnitude with the output of the oscillator (10) by means of diodes (52, 56) and a potentiometer (60) the slider of which supplies a signal to an automatic gain-control circuit (64) which controls the amplifiers (44, 46, 48). The a.g.c. level is set by removing the dielectric (20), earthing capacitor (26) with the switch (80) and setting the slider 62 to give zero output from amplifier (50). The phase difference between the measurement signal (81, Fig. 2, or 104 Fig. 4 not shown) and a signal from the oscillator, or from the output of the phase inverter (24), is determined by feeding the signals via capacitors (84, 85) respectively to opposite ends of a diode (86) and measuring the voltage thereacross with a meter (92). In the event of the measurement signal falling from its constant amplitude, due for example to too thin a sample of dielectric, the a. g. c. circuit is arranged to operate a relay (96) to short out the meter.
